I am a weeks owner of 5 Marriott timeshares since 1998. I have used the weeks each year. They are all enrolled in the destination club and I pay the annual fee of what a presidential designee pays. Today I placed my Maui week into the destination club in order to reserve some days in the new Waikaloa property. For me to get 7 days I was 50 points short of owning enough points so I had to settle for fewer days and had 500 points left which was 50 points shy of adding another day. My question is how can I preserve the 500 points without losing them. This is the first time that I have ventured into using the destination club as a resource and feel like that my doubts about not buying points have been justified as it appears that I will lose the 500 points if not used in 2020 or if banked and not used in 2021. It doesn't seem like I can use them in conjunction with the Marriot reward points and I can only buy 65% of marriot reward points using the destination club points. Am I missing something? I don't think I will be converting anymore of my weeks to the destination club in the future as it seems that I will never actually come out even in the unlikely event that I might chose to do so. Any suggestions from someone that is knowledgeable in the usage of points. Thanks for any help.
